Platform Market Share Over Time

mobilemagazine.gifThe paper version of Mobile Today has a Future Trends article by CSS Insight showing global platform market share over time…
It’s great to see the data over 2 years because it gives an indication of the share of devices currently in the market rather than those sold last quarter or last year. i.e. Assuming a 2 year replacement (I know many people keep phones longer) the area in the chart, for each respective platform, gives an approximate indication of the proportion of phones in use.
